Linux · Linux Kernel · CVE-2022-49527
**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
A null pointer dereference issue has been identified in the Linux kernel, specifically in the venus driver. The error occurs when `venus probe` fails at `pm runtime put sync`, leading to a sequence where `hfi destroy` is called before `hfi core deinit`. As `hfi destroy` sets `core->ops` to NULL, `hfi core deinit` cannot call the `core deinit` function, resulting in a null pointer dereference. This issue is resolved by skipping the call to `hfi core deinit` when necessary.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
